摘　　要：新设备在启动时需要进行带负荷试验,一般通过环网潮流或带用户负荷满足负荷要求,但受制于电网条件,有些情况下不具备带负荷条件。为此提出了一种通过调整并列运行的变压器分接头制造电压差的方法产生循环电流,通过理论分析和仿真计算验证了该方法的有效性,并将其应用于新设备启动实践。On-load test is needed for the new equipment start-up. Generally, the load is provided through the ring network power flow or the user load. However, it is subject to the conditions of the power grid, and in some cases, it does not have the load condition. This paper presents a method of generating circulating current by adjusting the voltage difference of transformer taps running in parallel. The effectiveness of the method is verified by theoretical analysis and simulation calculation, and it has been applied to the start-up practice of new equipment.
